Are there some debug hooks that can be activated? My sky2 stops responding (very light load) about twice a day. The netdev watchdog notices after a while and is able to reactivate the interface: Mar 15 13:28:12 btd kernel: NETDEV WATCHDOG: eth0: transmit timed out Mar 15 13:28:12 btd kernel: sky2 eth0: tx timeout Mar 15 13:28:12 btd kernel: sky2 eth0: transmit ring 458 .. 435 report=458 done=458 Mar 15 13:28:12 btd kernel: sky2 eth0: disabling interface Mar 15 13:28:12 btd kernel: sky2 eth0: enabling interface Mar 15 13:28:12 btd kernel: sky2 eth0: ram buffer 48K Mar 15 13:28:15 btd kernel: sky2 eth0: Link is up at 1000 Mbps, full duplex, flow control both This machine is a Core2 Duo e6700, and the interface is: 03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20) to 1 Gb hub. On a Pentium 4, with: 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 15) I have no issues, but with a very light network load, 100 Mb/s hub.. Each machine has two identical interfaces; only one has a cable in it. Both machines can be used for testing/debug. -- Rob
